I have recently switched from Windows 7 to Ubuntu. After I installed and replaced windows 7 it told me to restart. once I restarted, I came to a loading screen which says:

Unlocking the disk /dev/disk/by-uuid/33ebfb20-d2c-4738-80d3-0d34576dec03 (sda_crypt)
Enter passphrase:

after which there is a box. the problem is neither the keyboard nor the mouse works.
So how do I enter the passphrase without keyboard, or how do I get the keyboard working?

I was able to solve this by connecting the keyboard to the usb3 output.

The original poster reported in an edit that the problem was solved "by connecting the keyboard to the usb3 output."

That was it, I plugged the keyboard into a USB3 card and it started working. Keyboard worked fine in bios and during installation from an onboard USB2.
